day / time validation

[dwoske]

Suggest adding Date / Time validation rules, with a way to specify the format of the date, perhaps copy the https://golang.org/pkg/time/#Time.Format layout.

Are you looking for a string validator? Will regex rule work for you?

Or are you looking for a rule that validates the range of a date?

I suppose a regex can work.. something along these lines http://www.pelagodesign.com/blog/2009/05/20/iso-8601-date-validation-that-doesnt-suck/ .. lots of other versions of a date regex about as well.

But, actually, as I think more - a real date parser should be used, as it's not really possible to determine that 2016-02-31 is not a valid date.
